Bestselling novelist Ursula Hegi (Stones in the River) has moved from Scribner to S&S's Touchstone imprint, where publisher Mark Gompertz, her longtime editor, signed for her next novel. It's called Sacred Time and is a multigenerational story of an Italian-American family in the Bronx and Brooklyn over a half-century; Gompertz bought North American rights from Gail Hochman at Brandt & Hochman.... Sarah Jones, a dramatist and performance artist, is doing a book based on her Surface Transit show and two of her plays, and Chris Jackson at Crown bought it from Elyse Cheney at Sanford Greenburger.... A book about new Canadian golf hero Mike Weir, who just won the Masters, was a happy commission by publisher Doug Gibson at Toronto's McClelland & Stewart. He had assigned local golf columnist Lorne Rubenstein to follow Weir around for a book, little thinking he would win big; now he'll have a hot property come pub date in October. Gibson has North American rights, but agent Bruce Westwood at Westwood Creative will be entertaining U.S. offers.... Warner's Rick Wolff made a big buy of a book about the guru of business writers, 92-year-old Peter Drucker. It's tentatively titled Drucker: The Man Who Invented Business and will be written by top business editor John Byrne. Wolff bought world rights including audio, from Mark Reiter at IMG, for what will be an exclusive authorized bio.... Epic fantasy author Tad Williams is doing a trilogy called Shadowmarch for DAW Books, where Betsy Wolheim and Sheila Gilbert shelled out a seven-figure sum to Matt Bialer and Kimberly Whalen at Trident Media Group. There were concurrent sales to Time Warner U.K. and Klett Kotta in Germany; the total take is in the mid-seven figures.... Shannon Holmes, a hip-hop author who made a big underground hit with an independent press novel, B-More Careful, has now gone mainstream in a two-book deal with Atria's Malaika Adero, who preempted for six figures from agent Jimmy Vines, U.S. and Canadian rights; first of the new titles is Bad Girlz. A posthumous novel, his first, written for a YA readership by the late Stephen E. Ambrose, was signed from his estate by Brenda Bowen at Simon & Schuster Books for Young Readers. It's called This Vast Land: A Young Man's Journal of the Lewis & Clark Expedition and is based on a (fictional) diary by young George Shannon, who was actually on the expedition; Bowen bought it from Endeavor's Brian Lipson.
